UNITED STAT S PATENT JOSEPH BENJAMIN, OF BROOKLYN, NEW YORK, ASSIGNOR TOHIMSELF I AND THOMAS TIBBALL, OF SAME PLACE.

EDGE-FORMING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 249,875, dated November22, 1881 Application filed August 17. 1881.

To all whom it may concern Be it known that I, JOSEPH BENJAMIN, ofBrooklyn, in the county of Kings and State of New York,have invented anew and Improved Edge-Forming Attachment for- Sewing- Machines, of whichthe following is a full, clear, and exact specification.

The usual method of forming edge-seams of articles of clothing is tobaste down the turned edges, and then stitch them by machine. Deviceshave been used to press back the edge on the wrong side of the garmentand hold it while being stitched, but the right side of the garmentbeing underneath during the stitching, the shuttle-stitch is formed onthatside, which is highly objectionable.

My improved device is for forming the ed go and gaging the width of seamwhile the garment is stitched with the right side upward, as in the handoperation; and the invention consists in an attachment provided with afixed tongue and adjustable gage, as hereinafter described and claimed.

In the accompanying drawings, Figure l-is a plan View of the attachmentshown in its relation to the presser-foot and needle, and Fig. 2 is across-section of the attachment on line 00 w of Fig. 1. Fig. 3 is alongitudinal section of the material, having its edges turned.

Similar letters of reference indicate corresponding parts.

A is a plate provided with a slot, at, for the screw 1), by which theplate and the devices it carries are attached to the bed of the machine.

B is a slide attached on plate A by a screw, 0, passing through a slotso as to allow adj ustment in the line of the feed. These two adjustments permit accurate placing of the edger in relation to the needleand presser-foot. The slide B is formed with a rigid tongue, d, whichlies upon the bed of the machine and corresponds in thickness with thematerial to be sewed. There is also on slide B an adjustable T-shapedgage, e, held in place by a screw, f, and in contact at its lower edgewith the tongue (No model.)

d. The adjustment of gage c is at right angles to the feed, and variesthe projection of the tongue (1 beyond the face of the gage.

In the use of the attach ment the edge, turned as shown in Fig. 3, isplaced on the tongue d and beneath the presser foot, with the right sideof the garment upward. The under fold is then drawn outward until itrests on the bed, with the edge against the edge of tongue at, as shownin Fig. 2, the upper fold being against the gage e. The machine beingthen put in operation, the tongue (I will force the lower fold backcontinually as the cloth moves forward, and it will be stitched in thatman ner. By adjustment of the gage e the width of the edging isregulated, the line of stitching remaining the same, according toadjustment of plate A. The action of the tongue and gage is automatic inbringing the folds to the proper position for sewing, so thattheoperator is relieved from the'careful watching of the work andconsequent strain on the eyes. The right side of the garment beingupward, the needle -stitcl1 is upon that side, as is the case inhand-work, and a more finished edge is thus secured.

Having thus fully described my invention, 1 claim as new and desire tosecure by Letters Pat'ent l. The edging attachment for sewingmachines,consisting of slotted plate A, adjustable slide B, formed with tongue d,and the adj ustable gage, combined for operation, substantially as shownand described.

2. In an edging attachment for sewing-machines, the combination, withthe adjustable T-shaped gage c, of the adjustable plate B, provided withthe. tongue (1, corresponding in thickness with material to be sewed,substantially as and for the purpose set forth.

JOSEPH BENJAMIN.
